In this form of my invention, the body poreither direction from. itsnormal position.

and is centrally. located by a pair of-opposed springs SZand thefornicrof which corresponds to the spring 17 in the previous embodiment.The spring 32 is conlined be tween the upper surface of the body portion4 of the lock and afiange 3 which. is carried by the head of the bolt or:rod and the spring 33 is interposed between the bottom surface ofthebody portion 4 and a collar 31' which is carried by the rod '7. Belowthis collar, the bolt or rod is reduced in size and extends to withinashortdistanceof the sector or. gate 2 and has secured to its lower end aslide '37. by means of a projectio'n'38, which is'ot general U shape andwhich embraces the. edge of the lever l. The

slide is movably attached totlie side of the lever 1 by a rivet 39 whichpasses through the lever and through a bushing it) which is confinedbet-ween the headwof the rivet-and the surface of the lever 1. The

. outer end of the bushing overhangs the edge of a slot 41 in the slide37 and forms a spacer for the rivet 39't0 prevent its binding theslideS'T against the lever. This forms a cheap antlfcouvcnientmethod ofattaching the slide to the lever, and insures freedom of movement. llhen the parts are in normal position, or that shown in Fig. 7, the lever1 is free tomove into any branch of the Hshaped slot. 3 within thesector or gate 2 except the one which represents the re verse for theautomobile and which I have designated 3" in Fig. 8, the entrance of thelever into this portion of the slot being ordinarily prevented by theengagement of the lower portion of the slide 37 with the projection 2*oirthe sector or gate. :lhen it is desired to reversethe automobile, theslide 37 is elevated above the projection '2 by pulling upwardly on therod .7, when the slide may pass over the top of said PIOJQC- tion. Toexpedite this operation 1 make the head of the rod 7 in the form of aring into which the operator may'insert his finger. .-\'i'te r theinitial movement of the lever in reverse (liiecti ii. the parts maybereleascd. allowing the slide EST-to resume its normal position, theslide being auton'iatically elevated when returning to central positionby its engagement with the rear. inclined side Of-rthfi pro ection 2".

lock the leveagainst any movement other than a slight lateral shifting,the rod 7 is depressed as in theformer case to project the lower end ofthe slide 3'? into the slot 3, in which positionthe parts are held bythe cooperation of'tlie Yale lock and the notch within the rod 7*.

F 10 and 11 illustrate a form of my inventionwhei'ein the the principalmembers of my lock, while the body portion 4:2, which contains the Yale10, the body portion 432 is of general U shape in plan and embraces theforward edge of the lever 1, and it is secured to said lever by a'rivet'lti which passes through a slot in one side of the U-shaped bodvportion 42 and through a hole in the. lever.

Between the head of the rivet l3 and the ad-.

jacent side of the lever l, the bo'dv portion 42 is enlarged to form avertically disposed boss which is made hollow for the reception of acompression spring it that is adapted to hear agi-iinst the upper wallof the hollow boss and the rivet 43. This spring tends to elevate thebody portion 4.2 and withdraw its enlarged lower end 45 from the Slot inthe gate or sector To assist. the rivet 43 in accurately guiding thebody portion 42, I provide a pin 4:6 which extends through the lever 1*-and projects ateither end into vertical grooves onthe inner walls of thelegs of the Ushaped body portion 42. A

er 1 forms one of.

As will be seen from Fig. l

operates with the barrel of tl'ielock to retain the parts in lockedposition when the body portion 12 is depressed, in-tlie same manner asthe. notches in the 'rods' 7 and 7 The notch 15, to which reference hasbeen made hercinbefore, permits of the removal of the key after thebarrel 8 has been turned to the position shown in Fig. 3.
